The whole point of Twitter is to say something using no more than 140 characters. It's hard. What can be said?
When Jesus was asked to summarise the Law, he said, "The first commandment is this: ‘Hear, O Israel, the Lord our God is the only Lord. You shall love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength'," but it's 79 characters too long and therefore will not do. I cannot tweet the Good News with this form of words.
We might next turn to perhaps the most famous Bible verse of all. It's John 3:16, "God so loved the world that he gave his only Son Jesus Christ to save us
from our sins, to be our advocate in heaven, and to bring us to eternal life", but even this is 11 characters too long. Again, I can't tweet this message in full.
This Christmas, I'm turning to a verse from John's Prologue. John 1:14 says, "The word became flesh and dwelt among us". This is perfect because it says everything. And it's only 100 characters in length. It summarises everything that needs to be said about Christmas. And, furthermore, it says everything about the loving purposes of God.
